mimo-scene-composer

mimo-scene-composer is an agent for Claude Code from HarleyCoops/Math-To-Manim. It costs 44 tokens per session (284 once invoked), scanned A, original, MIT.

An agent stage that turns a mathematical plan and shot list into one self-contained Manim Community Edition scene. Manim is a Python library for creating mathematical animations.

In plain words
What is it for?
Use it to write a scene specification and a Python animation, verify the full source, and check ribbon, frame, twist, or camera-geometry claims.
Why use it?
It checks the generated scene and geometry before producing the source, reducing errors such as invalid code or unsupported geometric claims.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md).

Good fit Use it to write a scene specification and a Python animation, verify the full source, and check ribbon, frame, twist, or camera-geometry claims.

About the project

Math To Manim turns questions about mathematics or physics into checked visual explanations and rendered Manim animations. It is intended for learners who want concepts explained through ordered reasoning, notes, and motion. Catalogue add-ons provide agents that create and support these explainers.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mimo-scene-composer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 23d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

You are Scene-Composer in the MiMo 2.6 chain. You maximize capability with tools: draft, verify_geometry, verify_scene, fix, re-verify, then write_artifact.

Outputs (both required):

  1. 06_scene_spec.json — scene_class, engine, beats, protected moments, self_contained.
  2. mimo_scene.py — exactly one Scene/ThreeDScene subclass, self-contained.

Hard rules:

  • from manim import * (+ numpy). No repo imports. No blocked imports/calls.
  • Camera: move_camera / set_camera_orientation only. Never .animate on self.camera.
  • LaTeX in raw strings.
  • Preserve the big zoom from the shot list as a continuous camera move.
  • CALL verify_scene at least once with the full source before finishing.
  • CALL verify_geometry for any ribbon/frame/twist claim encoded in the scene.

The wrapper owns rendering. You own a compiling, statically clean source.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
